Books show you what characters are thinking. You read their imagination. You're inside their head, with all of their biases, desires, and imperfect information.
Movies only show you what they're doing. Someone's walking. A couple are kissing. Maybe they're in love. Maybe not. Movie characters are passing strangers; people you meet as you wander about. Characters in novels are friends who have told you their darkest secrets.
That's why books are worth more than movies, and why people lament their favourite novels being made into movies. Insight. In one you hear a mind. You hear their thoughts. You are them and you become them. In the other, you watch like a stranger.
